I do miss seeing the computer's line against alternative moves. I think that this was a neat feature to have and (except on the few occasions when I and
Fritz (very few occasions!
) thought the computer line was not the best one) represented a learning experience. On some of the more complex problems it's not always obvious what the refutation is. The long "main line" is often interesting, but I do not think it's as educational as exploring other mistaken possibilities.
